o.r. = of reading; 1 g/cc = 1 kg/l; T = medium temperature
• Mass flow and volume flow (liquid): ±0.05% o.r.
• Mass flow (gas): ±0.25% o.r.
• Density (liquid): ±0.00025 g/cc
• Temperature: ±0.25 °C ± 0.0025 · T °C; (±0.5 °F ± 0.0015 · (T–32) °F)
Influence of medium temperature
When there is a difference between the temperature for zero point adjustment and the process
temperature, the typical measured error of the sensor is ±0.0002% of the full scale value / °C
(±0.0001% of the full scale value/°F).
